In 2005, he won the Panamerican U10 championship with a perfect score of 9/9 points, namely winning all the nine games.[5][6] The following year, he won the Panamerican U12 championship[7] and tied for second place, placing fourth on tiebreak, in the same division of the World Youth Chess Championship.[8] In 2007 he tied for first (finishing second on tiebreak) in the Panamerican U12 championship[9] and shared 3rd–5th place in the world U12 championship.[10]

In the third game he didn't show up in time, as Cori, due to language barrier, misunderstood the start time (6:50 instead of 6:15), and was forfeited due to "zero tolerance" rule; he drew the fourth game and therefore was eliminated from the tournament.[25][26] Later that month, in August 2013, he placed second at the Open of Sants, Hostafrancs & La Bordeta in Barcelona, behind Baskaran Adhiban.[27] In September 2013, Cori tied for 3rd–4th in the World Junior Championship.[28] He tied for first place, placing third on countback, in the 3rd Panama Open with 7/9.[29] In December 2013, he placed equal second, fourth on tiebreak, at the World U18 Championship.[30]

In April 2015, Cori won the 6th Latin Chess Cup in Vicente Lopez, Argentina, edging out Axel Bachmann on tiebreak.[34] In May 2015, his first place the Zonal 2.4 Championship qualified him for the Chess World Cup 2015.[35] Later in the same month, he finished third in the 10th American Continental Championship in Montevideo.[36] Cori decided to not participate in the World Cup in order to compete for the last time in the World Junior Championship and his spot was taken by his sister Deysi, who finished third in the Zonal 2.4 Championship.[37]
